APHY 101 FINAL EXAM 2025 QUESTIONS
AND ANSWERS.
1. What is the difference between anatomy and physiology? - Correct answer-
Anatomy is the study of the structure of body parts, whereas physiology is the
study of the function of body parts
2. What are the levels of organization? - Correct answer-subatomic particles,
atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system,
organism
3. What are the requirements of life? - Correct answer-Water, food, oxygen,
heat, pressure
4. What are the characteristics of life? - Correct answer-Movement (internal or
gross); Responsiveness (reaction to internal or external change); Growth
(increase in size without change in shape); Reproduction (new organisms or
new cells); Gas exchange (use of oxygen; removal of CO2); Digestion
(breakdown of food); Absorption (movement of substances through
membranes and into fluids); Circulation (movement within body fluids);
Assimilation (changing nutrients into chemically different forms); Excretion
(removal of metabolic wastes)
, Page |2
5. Define homeostasis - Correct answer-Body's maintenance of a stable
environment
6. What is a homeostatic mechanism? - Correct answer-the body maintains
homeostasis through a number of self-regulating control systems; examples
are regulating body temperature and pressure sensitive receptors to regulate
body pressure
7. Define matter - Correct answer-Anything that takes up space and has mass
(weight). It is composed of elements.
8. Define element - Correct answer-fundamental substance composed of
chemically identical atoms
9. Define atoms - Correct answer-smallest particle of an element; basic unit of
matter
10.What is the structure of an atom? - Correct answer-An atom consists of a
nucleus containing protons and neutrons, with electrons in
11.orbit around the nucleus.
, Page |3
12.Atomic nucleus - Correct answer-the nucleus contains protons and neutrons
13.Proton - Correct answer-subatomic particle that has a positive charge
14.Neutron - Correct answer-subatomic particle that has no charge
15.Electron - Correct answer-subatomic particle that has a negative charge
16.Atomic number - Correct answer-number or protons in nucleus
17.Atomic mass - Correct answer-number of protons plus number of neutrons
18.What are covalent bonds? - Correct answer-Covalent bonds are formed when
atoms share electrons to become stable with filled
19.outer shells
20.What are ionic bonds? - Correct answer-2 oppositely charged atoms form this
bond when electrons are transferred from one atom to another atom
, Page |4
21.What are hydrogen bonds? - Correct answer-Weak attraction between positive
end of one polar molecule and negative end of another polar molecule;
formed between water molecules
22.Define ion - Correct answer-When atoms gain or lose electrons, they become
ions.
23.Define synthesis reaction - Correct answer-Two or more atoms or molecules
are joined together
24.Define decomposition reaction - Correct answer-Larger molecules are broken
down into smaller ones
25.Define exchange reaction - Correct answer-Parts of molecules trade places
26.Define reactant - Correct answer-The starting materials of the reaction - the
atoms, ions, or molecules
